My Bird was throwing code 23 and 54, I realized I forgot to plug the MAT sensor when I had the air cleaner base off. I plugged it back in and now my service engine soon light is off. What happened to code 54? Can one code trigger another?

 

Code 54 is likely to return, it is a failure of the fuel pump relay and/or circuit.

Thanks. If it comes back on I'll change the relay
